'10 ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that l, CHARLES A. KmLGR-EN, of Boston, in the countyofsSuolk, and State of Massachusetts, have invented an improvedPicture-Envelope; and I do hereby declare the same to be fully describedin the following specification, and represented in theaccoinpanyingdrawings, of which- Figure 1 is a perspective view of suchenvelope arranged for supporting the picture in an inclined positionupon a table.

Figure 2 is a vertical section of it and the picture or photographarranged Within it.

This envelope is composed of a piece or strip of paper folded twice,that is, .at the first and second'thirds of its length. One ci' theouter third parts has an opening made through it, and a pocket formed inrear of such opening, and open ai. me en/o., in order to enable apic-turc or card to be inserted in such pocket, so as to bc observedthrough thc opening when the latter may be uncovered. The other thirdsof thc strip of paper, Whenbent or folded upon the black of the pocket,and on the front of the opening, serve -as a flap or cover both to thepocket and the picture. v

In the dra-wings, A denotes the strip of paper, bent at a and 6 intothree parts, c d e. The iirst part e has an opening,f, made through itof a size somewhat less in area than that of the picture to be seenthrough it. A piece of paper, g, is to be pasted, at three of its edges,to theback of the part e, so as to form, with the piece e, a pocket toreceive a picture. When the part e is doubled between the parts c ol,they will cover it on its opposite sides, but when the three parts arearranged on the picture, as shown in Iig. 1, the parts a and d serve tosustain, in au inclined position, the picture, or the part e containingit. i

In some respects, my envelope resembles that exhibited in the UnitedStates Patent No. 35,861, that is to say, it has an opening through oneof its sides, and a ilap to cover such opening, but in my improvedenvelope the ap is made to cover opposite faces. of it, instead of asingle face, such serving to enable thc picture to bc4 protected tobetter advantage, and, when in an inclined position, to be sustained atboth ends by the rest of the iiap. i

- I do not,\tlierefore, clain'i the subject of the aforesaid patent.

What I claim as my invention is- The improved picture-envelope, madesubstantially as described, that is, with its flap folded, and of alength so as to be capable oi' being laid over both faces of the pocket,the same being as and for the object or purposes as hereinbeforeexplained.
